OBJECTIVE QUESTIONS
Mark(✓) against the correct answer in each of the following:
1. A fraction equivalent to 35 is
(a) 3+25+2 (b) 3-25-2
(c) 3× 25× 2 (d) none of these
Solution: Correct option is (c) 3× 25× 2
3×25×2 = 35
2. A fraction equivalent to 812 is
(a) 8+412+4 (b) 8-412-4
(c) 8÷ 412÷ 4 (d) none of these
Solution: Correct option is (c) 8÷ 412÷ 4
Because when we divide or multiply the numerator and denominator by same number, we get an equivalent fraction.
3. A fraction equivalent to 2436 is
(a) 34 (b) 23
(c) 89 (d) none of these
Solution: Correct option is (b) 23
Because, 2436 = 24÷1236÷12 = 23
4. If 34 is equivalent to x20 then the value of x is
(a) 15 (b) 18
(c) 12 (d) none of these
Solution: Correct option is (a) 15
∵ 34 = x20
⇒ 4x = 3 × 20 (by cross multiply)
⇒ x = 3×2054 = 15
5. If 4560 is equivalent to 3x then the value of x is
(a) 4 (b) 5 (c) 6 (d) 20
Solution: Correct option is (a) 4
∵ 4560 = 3x
⇒ 45 × x = 3 × 60 (by cross multiply)
⇒ x = 3×6045
⇒ x = 180445
∴ x = 4

(a) 34 < 35
(b) 34 > 35
(c) 34 and 35 cannot be compared
Solution: Correct option is (b) 34 > 35
If fractions having same numerator, then one with the smaller denominator is the greater.
